For each IGI entry there is a specific batch number and serial sheet number. These are coded addresses for the original data, usually several lines of a Register that has been filmed by the LDS Church.
If you want a copy of that entry then you may order it from Utah. Order Sheet #31831, "Request for Photocopies: IGI and Sources" is available freely at LDS Family History Centres. By air, the turnaround time is about 4 to 6 weeks.
You must include on the form, the full coded address for each item. If you have used the fiche style IGI, then you will have to consult the Batch Number Index, a small set of fiche which converts the batch number into an input source [microfilm] serial number. This is the number needed in Utah, to quickly and reliably find your entry.
Most batch numbers have 6 digits and an alpha prefix, for example, C for Christening, M for Marriage. Images of these register entries may be had from LDS at Salt Lake City very cheaply, US$ 2.00 each.
Some batch numbers have no alpha prefix but are of 7 digits, for example, 8604703. If you find such a number against a name you are researching, then you may have an exciting time ahead...
These non-alpha numbers identify Patron Submissions. A researcher has provided the entry from his/her own research, which may, for example, be from an old family Bible, or from a register not microfilmed.
The first two digits of the batch number represent the year. For example, in the case of Batch 8604703, a patron gave the information in 1986.
The copy of that Patron's submission will cost you US$ 0.25. The order form has space for 8 requests, that is, US$ 2.00 worth. The versatile form facilitates the ordering of other types of sources too.
The Patron's submission will include postal address and sometimes, other entries additional to the one you requested. The Patron may be from your own family, for example, a distant cousin with whom you can exchange details.
